Chapter 10 Analog Comparator (RS08ACMPV1)
NOTE
Comparator inputs are high impedance analog pins which are sensitive to
noise. Noisy VDD and/or pin toggling adjacent to the analog inputs may
cause the comparator offset/hysteresis performance to exceed the specified
values. Maximum source impedance is restricted to the value specified in
Table A-6. To achieve maximum performance device is recommended to
enter WAIT/STOP mode for ACMP measurement and adjacent pin toggling
must be avoided.
